Depend on the distribution of shared system resource between different processes, the conflict in the utilization of resources can take place.Because many different processes can be handled simultaneously, two or more processes may need to visit given shared system resource fully simultaneously.But if resource and that process that given process has obtained to use stop because of certain reason is unexpected, the resource of Huo Deing becomes and can not obtain other process so, causes the poor efficiency of processing environment.
For example, the given process of moving on thread can be used for example shared system resource of Mutex object.To such an extent as to Mutex object is to pin a blocks of data to have only a thread can control the object of those data of determining at any time.Obtain this blocks of data because many threads can wish to visit Mutex object, so it is the shared system resource.If thread stops suddenly, to such an extent as to thread has no chance to stop its state, share so that Mutex object meeting " is locked in the outside " thus and can not visit this Mutex object and the use of its companion data with other thread of other process context.This situation can need to stop fully one or more processes and allow shared resource to be " released " so that other process can obtain this shared resource.In another kind of sight, the time span of one section expansion of process meeting " circulation " is used the shared system resource, and has therefore stoped other system process to visit this shared system resource.In some cases, even need restart total system and allow shared resource can obtain again to handle.
If the work of Zu Saiing can hinder other request of server process and all scheduling threads have all blocked like this, it may finally stop fully.If the current solution that this problem is used is to finish time of waiting for specified amount and do not finish with regard to the kill server process in that time as request.This method has spinoff unfortunately, and promptly it has also stopped any other and has sent to the request of apps server.
Therefore, needed is distribution and the administrative mechanism that is used for distributing effectively and controlling the shared system resource of shared system resource.
